I've seen these and others fail over and over. http://answers.microsoft.com/en-us/office/forum/office_2010-office_install/office-2010-update-kb2825635-several-times/777b16e3-a35c-47e8-a349-2fc6deacf4db shows a frustrated person that I guess does not want to look into any issue other than a fix.
There are many prior discussions on this so I can't tell which answer you are seeking. As always, Microsoft provides options for ignoring updates. That's one fix.
There are two updates one for MS Office 2010 (KB2825635)and one for Office File validation 2010 (KB2553065). These two constantly appear in the update folder. And everytime I reboot my computer they are both reinstalled. I did a clean installation of Windows 7 on April 7 and these two updates were installed on that date (along with many others). There are over 50 installations of these updates. How can I get rid of them and how can I stop the reinstallation.
